Is there anything incompatible when going from 2.6 to 2.7?  Because it does
mean that you need to change all scripts in lockstep with the distro upgrade,
because 2.7 is not in squeeze and 2.6 is not in wheezy, unless(!) python2.6
from squeeze is still installable in wheezy (i.e. no conflicts etc.).  The
reason to have two versions of 2.x was to avoid this lockstep, especially as
scripts tend to specify their Python versions in the shebang.

If an upgrade does not force python2.6 (and the corresponding python2.6
modules) to be uninstalled, I think it's fair to drop it from wheezy.  But
somehow I'm sceptical, that this is true.

Kind regards
